NSF CERTIFICATION
These merchandisers are manufactured to meet
ANSI / National Sanitation Foundation (NSF®)
Standard #7 requirements. Proper installation is
required to maintain certification. Near the serial
plate, each case carries a label identifying the type
of application for which the case was certified.
ANSI/NSF-7 Type I – Display Refrigerator / Freezer
Intended for 75°F / 55%RH Ambient Application
ANSI/NSF-7 Type II – Display Refrigerator / Freezer
Intended for 80°F / 55%RH Ambient Application
ANSI/NSF-7 – Display Refrigerator
Intended for Bulk Produce
LOCATION
These merchandisers are designed for displaying
products in air conditioned stores where tempera-
ture is maintained at or below the ANSI / NSF-7
specified level and relative humidity is maintained
at or below 55%.
Placing refrigerated merchandisers in direct sun-
light, near hot tables or near other heat sources
could impair their efficiency.
Like other merchandisers, these are sensitive to
air disturbances. Air currents passing around
merchandisers will seriously impair their opera-
tion. Do NOT allow air conditioning, electric
fans, open doors or windows, etc. to create air
currents around the merchandisers.
Product should always be maintained at proper
temperature. This means that from the time the
product is received, through storage, preparation
and display, the temperature of the product must
be controlled to maximize the life of the product.
The exterior frames on these cases provide space
for air circulation. However, in high ambient
conditions, sweating may still occur. If this
happens install a method of forced ventilation
such as a fan ventilation kit.
SHIPPING DAMAGE
All equipment should be thoroughly examined for
shipping damage before and during unloading.
This equipment has been carefully inspected at
our factory. Any claim for loss or damage must be
made to the carrier. The carrier will provide any
necessary inspection reports and/or claim forms.
Apparent Loss Or Damage
If there is an obvious loss or damage, it must be
noted on the freight bill or express receipt and
signed by the carrier’s agent; otherwise, carrier
may refuse claim.
Concealed Loss Or Damage
When loss or damage is not apparent until after
equipment is uncrated, retain all packing materials
and submit a written request to the carrier for
inspection, within 15 days.
EXTERIOR LOADING
Do NOT walk on top of merchandisers or
damage to the merchandisers and serious
personal injury could occur. THEY ARE NOT
STRUCTURALLY DESIGNED TO SUPPORT EXTERNAL
LOADING such as the weight of a person. Do not
place heavy objects on the case.
INSTALLATION
Do not walk or put heavy objects on case.
CAUTION

MERCHANDISERS SHIPPED
WITH END INSTALLED
Be careful not to damage the factory installed end
while moving the case. Tools must be positioned
past the end and beneath the merchandiser’s
support bar.
SHIPPING BRACES
Move the merchandiser as close as possible to its
permanent location and then remove all packaging.
Check for damage before discarding packaging.
Remove all separately packed accessories such as
kits and shelves.
LEVELING
Merchandisers must be installed level to ensure
proper operation of the refrigeration system and
to ensure proper drainage of defrost water. When
leveling merchandisers, use a carpenter’s level as
shown. Leveling shims are provided with each
merchandiser for use if needed. The shims are big
enough so that you can level adjoining merchan-
disers at the same time using one shim.
NOTES:
• BEGIN LINEUP LEVELING FROM THE HIGHEST POINT
OF THE STORE FLOOR.
• If shimming two corners, check to see if a shim is
needed in the center of the merchandiser. If a gap
exists between the support rail of the merchandiser
and the floor, a shim should be placed in the center.
Do NOT remove shipping braces until
the merchandisers are positioned
for installation.

the top as shown. Be sure to lap gaskets as
shown. Check to be sure that there are no
gaps between gasket and merchandiser.
Fasten Cases
1. Move the second merchandiser into position
against the first. Match the alignment rod
and pin with the corresponding holes.
2. Fasten fronts together using cap screws, flat
washers, lock washers and nuts. Tighten
only until front panels touch. Do not tighten
fully.
3. Use the cap screws, flat washers and lock
washers provided in the joint kit to draw
the merchandisers together at rear. Do not
tighten fully.
4. Tighten joints in the order shown (A, B, C,

Join Plexiglass
Parts List
• Acrylic Solvent Cement (IPS Weldon #40 or
comparable, mixing instructions on product)
• Masking tape and duct tape (not supplied)
Instructions
1. Prepare front plexiglass for cement applica-
tion by placing masking tape not more than
1/16 in. (6 mm) from the seam, on both sides,
front and back. Tape is to protect plexiglass
from cement spill over. Scarring will occur if
cement touches clear plexiglass.
2. Separate front plexiglass pieces enough to
apply a bead of #40 cement down one edge
inside of seam.
3. Apply cement with applicator to one or both
surfaces. Join immediately.
4. Realign front plexiglass and push together
tightly.
5. Apply just enough pressure to remove any air
bubbles. Do not squeeze joint so hard as to
force cement out of the joint—a dry joint may
result.
6. Apply tape (2 in. duct tape recommended)
across face of seam to secure plexiglass from
shifting while cement dries.
7. Allow approximately 4 hours to dry at 70°F.
Seal Merchandisers
1. Apply butyl tape across the bottom joint. Be
sure to extend the tape up the back and front
of the case.
2. Use field-supplied silicone to fill any gaps
between the front support brackets.

INSTALLING BUMPERS
Elite bumpers are shipped as a continuous roll.
Once installed the continuous bumper helps to
disguise the joint locations, giving the lineup a
smoother look.
1. Unroll the bumper and allow it to rest at room
temperature for 24 hours prior to installa-
tion to minimize bumper shrinkage after
installation.
2. Slide end caps onto retainer at right and left
ends of lineup. Align with slot in retainer,
then fasten with screws provided.
3. Measure the distance between inside end of
caps and add 1/8inch (3 mm) for each 4 ft
(1220 mm). Adding the additional material
will compensate for stretching which occurs
during installation.
4. Cut the bumper to length with a miter saw for
a precise, right-angle cut.
5. Lubricate the inside of the vinyl with soapy
water or silicone spray.
6. Starting at the left end of the line up, butt end
of the vinyl bumper against end cap. While
applying pressure, bend back vinyl top so that
vinyl legs are positioned within the base
grooves. Roll vinyl bumper over full length of
retainer, then tap with rubber mallet to ensure
vinyl is securely locked into retainer.
7. If necessary wipe clean with any household
cleaning product.
INSTALLING PARTITIONS
To join same temperature fixtures on different
defrost cycles, an acrylic partition kit is
required.
To join unlike fixtures, or like fixtures operating
at different temperatures, a 1 in. (26 mm)
insulated connecting partition kit is required.
Instructions for installing these partitions are
included with the kits.

REFRIGERANT
The correct type of refrigerant will be stamped on
each merchandiser’s serial plate. The case refrig-
eration piping is leak tested, factory sealed and
pressurized. Before making refrigeration hookups,
depress the universal line valve to ensure that
coils have maintained pressure during shipment.
REFRIGERANT PIPING
Connection Location
The refrigerant line connections are at the right-
hand end of the merchandiser (as viewed from
the front) beneath the display pans. A sticker
marks the location of the connection “pod.” The
installer must saw a hole through the pod to exit
the case.
After connections have been made, seal this outlet
thoroughly. Seal both the inside and the outside.
We recommend using an expanding polyurethane
foam insulation.
Multiplexing
Piping of merchandisers operating on the same
refrigeration system may be run from merchandis-
er to merchandiser. DO NOT RUN REFRIGERANT
LINES THROUGH MERCHANDISERS THAT ARE NOT
ON THE SAME REFRIGERATION SYSTEM BRANCH as
this may result in poor refrigeration control and
compressor failure.
Interconnecting piping inside the merchandiser
must be located as shown below to allow room
for lifting the hinged fan plenums and for
clearance beneath the display pans. Or the inter-
connecting piping may be run outside the case in
the raceway area shown.
Line Sizing
Refrigerant lines should be sized as shown on
the refrigeration legend that is furnished for the
store or according to ASHRAE guidelines.
Refer to the information on the next page for
branch line piping of Hussmann Equipment.
Oil Traps
P-traps (oil traps) must be installed at the base of
all suction line vertical risers.
Pressure Drop
Pressure drop can rob the system of capacity. To
keep the pressure drop to a minimum, keep the
refrigerant line run as short as possible using a
minimum number of elbows. Where elbows are
required, USE LONG RADIUS ELBOWS ONLY.
REFRIGERATION / ELECTRICAL
Refrigeration lines are under pressure
and should be depressurized before
attempting to make any connections.

INSULATION
The suction and liquid lines should be clamped or
taped together and insulated for a minimum of
30 ft (9144 mm) from the merchandiser.
Additional insulation for the balance of the liquid
and suction lines is recommended wherever con-
densation
drippage is objectionable or lines are exposed to
ambient conditions.
SUCTION LINE
• Pitch in direction of flow.
• May be reduced by one size at one third of
case run load and again after the second third.
Do not reduce below the case suction line
size.
• Case suction lines should enter at the top of
the branch line.
LIQUID LINE
• May be reduced by one size after one half the
case run load. Do not reduce below the case
liquid line connection size.
• Take-offs to case liquid lines should exit the
bottom of the branch liquid line. Provide an
expansion loop for each evaporator take-off
(minimum 3 in. [76 mm] loop).
